I'm using Powershell to check last backup times across all our sqlserver databases. This seems to work really well, but I've got a question
If I run this (a cut-down version of the actual script):
dir SQLSERVER:\SQL\Server1\default\databases | select parent, name,
lastbackupdate
I get:
Parent Name LastBackupDate
------ ---- --------------
[Server1] ADBA 10/09/2012 21:15:37
[Server1] ReportServer 10/09/2012 21:00:17
[Server1] ReportServerTempDB 10/09/2012 21:00:18
[Server1] db1 10/09/2012 21:15:35
If I then run a sql backup of the Server1 default instance, and run the same query the last backup date doesn't change:
PS C:\temp> dir SQLSERVER:\SQL\Server1\default\databases | select parent, name,
lastbackupdate
Parent Name LastBackupDate
------ ---- --------------
[Server1] ADBA 10/09/2012 21:15:37
[Server1] ReportServer 10/09/2012 21:00:17
[Server1] ReportServerTempDB 10/09/2012 21:00:18
[Server1] db1 10/09/2012 21:15:35
..but if I open a new powershell window, it shows the backup I just took:
PS SQLSERVER:\> dir SQLSERVER:\SQL\Server1\default\databases | select parent,
name, lastbackupdate
Parent Name LastBackupDate
------ ---- --------------
[server1] ADBA 12/09/2012 09:03:23
[server1] ReportServer 12/09/2012 08:48:03
[server1] ReportServerTempDB 12/09/2012 08:48:04
[server1] db1 12/09/2012 09:03:21
My guess is that this is expected behaviour, but could anybody show me where it's documented/explained - I just want to understand what's going on.
This is running the SQlps which came with 2008, against a 2008 instance.
Thanks
Matt
